STALK-CUTTER.

Terrill it may concern: LBe itfknown that I, Binzxx'r, P. Hummegi oina citizen of the United States, residing at Morvemvin ,the county of Brooks and State: of Georgia, have invented new and useful Improvements in Stalk-Gutters, of which the following is a specification.

jjr ie; present invention has reference to in; 'rovements i'n stalk-cutters, and it compre iendsan improved cutter designed prim arilyjor attachment to a disk harrow bet-iveen and in front of the two series of the cutter having a positive connection withtheshafts on which the disks are mounted whereby it :is maintained in fixed position relative to said disks.

, stalk cu't-ter per se s cri ption beyond-the fast. thateach' of as;

smite invention; further contemplates the pgqdtlct-ion of atstfilk-cutt ing attachment of the.;; .type:--specifiedwwhich is susceptible of accurate bodily,adjustment with respect to thegbeamffromwhich it is suspended, so as to enable it to be brought into the desired position relative to said disks, as above stated,-:after the latter themselves have been adjustedqinconformity to the particular strip of ground to betreatcd.

;-Eina'lly,- the-said invention resides in eertaindetails of construction of the component parts-of the attachment, and'in the specific 'con'neetion and arrangement of such parts.

A structural embodiment of the invention is illustrated in the accompanying drawings, -wherein Figure 1 is a perspective view of the improved stalk-cutter; Fig. 2 is a rear elevation'thercof with parts in section; Fig.- 3-is a side elevation of the stalk-cutter attached to' a disk harrow, the latter being shown diagrammatically and partly in section; Fig. 4 is a plan view of Fig. 3; and Fig. 5 is a side elevation of a modification.

In said drawings, A designates in a. general-manner the invention proper, i. e., the and B the machine or implement to which the cutter is attached, the said machine being here shown as a disk harrow of conventional type'comprising the beam' 1' thereon, and the two harrow sections 3 and 4 carried by said frame. The entire" harrow i'sshown diagrammatically, as has been already "stated,- ;.o\vi ng to its conventional construction, and requires no extended de- Specification of Letters Patent.

and to each other. to suit the particular field or strip of ground over which the machine is traveling.

The-stalk-cutter A comprises primarily an inverted U-shaped frame 8 suspended from an auxiliary beam 9 and formed by a pair of bowed metal straps whose upwardly-bent inner ends are disposed against the side faces of said beam and adj ustably connected thereto by a bolt 10 which passes through a transverse bolt holev in the beam and has its ends interchangeably engaged in the pairs of alining perforations 11 formed in said strap ends, the beam itself being disposed beneathand parallel with the main beam 1 and fastened to the same by a clip 12 or similar device, as shown in Figs. 3 and 4. The lower out-turned ends of the said straps are formed with alining perforations 13. or longitudinal series of perforations, wherein are engaged a pair of bolts 14 which are also engaged in perforations 15 formed in the outwardly-bowed rear portions of a pair of braces 16 who e front ends are upturned and connected by a bolt 17 to the front end of beam 9, said brace ends being likewise perforated, as indicated by the numeral 18. The several connections just described are, therefore, of such a nature as to permit frame 8 to be raised or lowered and, also, to be rocked to a slight extent upon bolt 10 as a pivot, and connected to the braces 16 at different points, owing to the formation of the perforations 15 in said braces.

The stalk-cutter proper, which, in the construction shown in Figs. 1 and 2, is located directly between. the members of frame 8, consists preferably of a series of radial blades 1 vill'l'illlfi8d longitudinally of and fastened to a hollow cylinder 20 in whose ends are fitted. a pair of heads 21 loosely mounted on a horizontal shaft 22. Each of said heads is, in turn, provided with a dust cap.23 which ,fits vlooselythereon and is formed with a pair of clips 24 or the like ar-' rangcd. .to,engage theadjacent strap or" fra e me ber, wherebysaid, caps are held against' rotation. Shaft 22 projects at its ends through registering perforations in said ca s and frame members.

' Owin'g to the direct connectionof the stalk-cutter to frame 8, the adjustment of the latter, as above described, willtelfect a corresponding yertical movement and also a slight lateral rocking movement, forward or backward, of said cutter. \Vhere the construction shown in Figs. 1 and 2 is followed, the adjustment of said frame is effected by separately fitting the several bolts inthe proper perforations, but, if preferred, the cutter may be detached from its frame and connected with a mechanism whereby it may be raised and lowered independent of any adjustment of said frame. In such instance, a pair of downwardly-curved arms 25, between which the cutter is'disposed, are pivoted at their front ends to the braces 16 in advance of frame 8, and are engaged adjacent their rear ends by the clips 24 on the caps 23, asshownin Fig. 5, the rear ends of said arms being pivotally connected by links 26 to a second pair of arms 27 rigidly secured to a rock shaft 28 journaled in said frame. Shaft 28 is operated by a lever 29 fastened to one end thereof and held in adjusted position by a suitable pawl and rack mechanism. The two strap members which comprise frame 8 are formed with alining perforations, lo .ated above the series of perforations 13, herein the ends of shaft 28 are received, and the swinging arms 25 are likewise formed with perforations through which the ends of shaft 22 extend.

.The stalk-cutting attachment as a Whole isdisposed between and .in front of the two barrow sections 3 and 4, and is designed to be connected directly to the same, so as to insure its being maintained in proper position relative to said sections during the time that the machine is in operation. To this end, there is slidably mounted upon the rear portion of each of the braces 16 a rearwardly-extending hook 30, or thelike, held in adjusted position by any suitable means. These hooks are adapted to engage the inner end portions of the corresponding disk shafts 6, as shown in Fig. 3, the arrangement being such that the weight of the sections will be exerted directly, upon said braces, and, consequently,. upon the cutter, which latter is thus held against displacement and its blades causedto enter the soil to the same depth as the disks, it being understood that the adjustment bf said cutter is effected subsequent to that of the disks and in correspbndence therewith. The said sections, moreover. are so arranged that the front portion of the innermost disk of each section projects into the space between the rear portions 'of said braces. It will be seen, therefore,

that when the machine is in operation, the.

cutter will act in advance of and between preferred position with reference to the main frame, and the cutter then positioned correspondingly. Finally, it may be stated that the attachment is susceptible of connection to and removal from the harrow.

I claim as my invention:

1.. A stalk-cutting attachment for .two-
